'Be'it'known that IILAURENGE E. Tor- RAM, a citizen of the UnitedStates, residing -at Swampscott, in the county of Essex and 5 iState-"ofMassachusetts, have invented certainanew and useful ImprovementsinInsoles; and I do hereby declare the following toabe a full, clear, .andexact description of the inventiomr such-as will enable others Skilledin the-art to'which it appertains to "lmake and usathe same. =JIh-isin'ventioifl-i'elates-to insolesfor boots @and'ishoes' andwmo're'particularly my what are knownrzeo'mmereially as manufactured 1 5'fin'so'les. I: Suchi insoles are generally produced if-rom two or inorelayers of Sheet insole maitenal and whenws'o constructed are calledolar'ni'nated "insoles; :The improvement here- .zinaifter describedis-applicable especially to flaminated insolesw 5 '!:1-'In*- the.manufacture of laminated insoles for welt shoes it has heretofore beencusftomai'yvtdbuild a body-portion of several layers of ins'olematerial, the 'combined zb'thickfiess of=whieh forms the feather out--"-side the marginal sewing-rib. This feather thickness has'been uniformthroughout the "periphery ofthe' feather. The thickness of:

the npper 'materials, which are lasted into theiangle formed'by -thesewing-rib and feather and over the heel'end of the insole, is notuniform, however,"there being a convisiderable extra'thicknoss at theend portions w: l --o'f. the upper caused by the insertion at the toe ofthe box-toe and additional toe stiffening materials, and the insertionat the -heel of the-:counter the forward ends of :aiwhih overlap-therear ends of the sewingi rib; ar Byareasonof thisthe welt, when seated40 mponrthe upper, 'theshoe being then in' insidrable -difiicultyisexp'erienced by the v operato'rof rthe 'inseaming-machine in sewingaround the toe and adjacent the breast line. If the operator sews high,which- "isa-nat ural consequence of the raised posi- 'tion'of the welt,a weak inseam results and consequently-when the 'outsole is attached thelatter is held above its proper plane at the toe and the correct line ofthe shoe is lost. 'If-thesewing-rib is too low to permit the welt to besewed high, the operatm W111 pfi eshoe so as to sew fulland "st1tchithus formed through the rib or between substance will-be exposed in the:welt crease of-the complete'd shoeg -pro- "duc lng what is=termed agrinning? inseam which detracts from the appearance: ofthe :s110e.-,.- vproduce a laminated =1ns0le having a=-=fe'ather 'wh ehjisefitted 'so as'to overcome" the difiirculties' incident to the "operation i of' Servingthe ruprperflimaterialsrto'the insole because The object of the resentinvention as to" =of the variation in the thieknem of the 'uppermaterials just referred to, and which will result m s'uperror's'hoemaking on any type of-shoe.

In accordance 'withthis object nature of the present invention providesthat; the

feather" of the insole shall so" fitted that room is-provided for theextra; upper materials wherever they occur with the iesult that in welt'shoes-the welt lies'properly against the sewing-rib 'and i-nslires aninseam at a unifonn 'height above the *tread face of theins0le,wher'eby' the proper lines ot the shoe are preserved. To thisend' it is-proposed to reduce ithe thickness of the featherwherenecessary by removing a portion" of one of the layers of ins'olematerial which are-used to constructfthe larnihated insoles- Such areduction infeatherthie'kness is provided, as-herein shown, about thetoe, substantially from one 'e'ndofthe tip line to its other end and,preferably, also ,at-eaehfside of the shank for a short distanee forwardof the breast-line: I Prefer- ='ably thelayerwhich-provides the sewing-"rib will not'be' distiirbedfthe reduction be-' ing made in a'body-layer and the width of the portion removed measured inward 4 from"the edge of' the solefwill substantially equal to I the :width of the"feather;- r In a laminated-insole composed offthree layers thereduction will preferably be made in the central layer; Thoseskilled'in' the art will "recognize that-an=insole havingthecharacteristics defined will'add qualitywaeouracy'and perfection toshoemaki'ng sin'oe its" use overcomes all irregularity and lack of"uniformity heretofore present in sewing the upper to the insole.

The invention comprises an insole having the novel features ofconstruction hereand Fig. t is a frag mentary view, in perspective,showing the method of reducing the feather at the toe.

The type of-insole illustrated in the drawings is a laminated insole forwelt shoes composed of three layers of insole material. Although nospecific kind .of material as essential, it is preferred to use atextile abric,"such as duck. for one outside layer 5 forming-thesewing-surface, said la.yer being provided with a. marginal sewing-rib6, which may be molded therein at the desired location relative-to theedgeof the insole, and -a=feather- 7. The remaining layers formthevbody-layersythe other outsidelayer 8 formingth'e sock-surface beingpreferably a leatheriskivingjiiequal in area to the? area of thennribbed or smooth face -of-the layer 5. The central body-layer 9 ispreferably a leather substitute, such as fiberboard. and

-.-i5 50 fitted as to permit the operator of" the iii-seaming machinetosew the seam at auni- =fqrm--height relative to the face of the msoler-thuspreserving the correct lines in the finished shoe, as. alreadyexplained.

;-T he-fitting of the body-layer 9 consists in shaping the blank toprovide an area equal to the-area ot the unribbed face of the layer 5-,or ofthe layer 8. exceptat the toe or at the heelendzof the shank justforward of the :breast line but preferably atboth ends. Thepurpose ofthis special fitting is to pro- -vide. a reduction in the thickness ofthe .feather at the'portions of the insole where the overlasted uppermaterials are increased in thickness by reason of the addition of 45.

stitfeningmaterials such as the box toe and counter; and thus compensateor make room for the reception of such extra thickness. Aocordingly a-strip extending completely around the to'e-isremoved or omitted fromthe margin of the body layer 9. as T shown '1 besti in Fig; 4 the recess10 thus formed terminating substantially at the ti line, in-

tlicatedby the shoulders 11- and 12. since sthe increased thickness ofupper-materials at the toe does not extend back of this line.

--The: feather '7 ofthe. sewing-surface then flies in contact with thesock-surface layer throughout the recess 1.0 forming a-feather of:buttivo layers about the toe whereas adj'acent portions of the featherare formed ,of-iolt three layers, The advantage accru- -.ing;=fr0mfitting the insole in the manner just described will beapparent .tothose skilledin the art from an inspection of Figs.

2; and-3;.;;F shows :an inseam sewed high and the consequent distortionin the line of the welt crease due to the abrupt rise at the tip line onto the box toe where the insole feather is of uniform thickness, andFig. 3 shows the even line of the inseam obtained when theinsolebf'the'pres'nt inv ntion is used, thus preserving the correct iineof the welt crease and-providing an even surface on which to laythou'tsole.

The same .difiiculty with respect to the 5 proper lay of the inseamoccurs, as already ointed out. at the heel end of the insole due to theact that the forward ends of'the counter must be lasted tothe sewing-ribwhere said ends project forwardly beyond so the breast line. Accordinglymarginal F- strips are removed or omitted fromatlle body-layer 9adjacent the rear ends of'ithe sewing rib, asshow'n best in Fig'. 1'where the sewing-surface 5 is broken away-atone side to show one of therecesses' 13 and 140i thus formed. These marginal-strips are ofsubstantially the same width as the feather, like the stripremoved'fmm'the amend the same advantages are secured from -the'irmemmaland consequent 'reduotion' in fe'athern ll'iir'k'ness as are'secured atthe toe end of the insole. Preferably the rear ends lfiiand J6 of therecesses 13 and 14mm beveled to avoid I a shoulder where the' counters'runs up on to the heel-seat which if present-would interfere with aproperrlaying--of-:the'but- It is believed unnecessary to' descri benthepmcess of manufacture of sthe iinsole except to say that the threelayers are preferably" formed separately to the desired-shape, theSewing-ribfi for a welt insole being molded in the layer 5 and themarginal'istrip or strips being removed or omitted :from'tho la yer 9prior to the assembly of-thelayersu ml ea h other. \vhenassembledthelayers are serured together, preferably by an adhesive applied at someconvenient time. and, in the process of making, the insole mixy'bemolded to any desired contour. a Y
